Background: Accelerometers and global positioning system (GPS) units to monitor participants’ activity allow for a dynamic spatial examination of the locations where physical activity occurs. The application of spatial clustering analysis to these geographically linked physical activity data may provide a better understanding of how moderate-to-vigorous physical activity (MVPA) concentrates ...
Background Children's current physical activity levels are disturbingly low when compared to recommended levels. This may be changed by intervening in the school environment. However, at present, it is unclear to what extent schoolyard physical activity contributes towards reaching the daily physical activity guideline. The aim of this study was ...
Introduction With increasing interest in how the physical environment may influence physical activity, methods are needed that can be used to investigate the environmental context of activity. The aim of this study is to use combined accelerometer and GPS data to describe the level and location of children’s physical ...
Introduction Combining GPS and accelerometer data offers a new opportunity to objectively measure children’s time spent active outdoors [1]. This is important as greater time spent outdoors is related to reduced risk of obesity. We know little about what factors determine children’s outdoor activity. This study uniquely investigated the ...
